摘　　要：针对雷达模拟操作训练中对雷达回波模拟的逼真度、实时性和交互性要求,提出了一种雷达回波实时仿真的设计方案。基于雷达信号接收、处理的工作原理,对雷达工作方式和战场环境分别建模,利用信号幅度特征对雷达回波进行功能性仿真。仿真中增加了与外部交互的接口,可实时响应外部雷达操作命令或背景变化产生的不同回波信号,提高雷达模拟操作训练中的实时交互灵活性,更接近实际背景。仿真结果接近真实回波表明,该设计方案具有一定的实用性。To improve the video fidelity and the practicability of real-time radar echo signal simulation for radar operation training,a new functional simulation scheme is presented.Based on the principle of radar signal receiving and processing,firstly,the radar work mode and the battlefield environment are modeled.Then,the character of the signal amplitude is extracted to realize functional simulation of the radar echo signal.Besides,some interactive interfaces are designed in the shceme to improve external radar operating instruction and changing environment by producing varied radar echo signal,thus improving the functional agility and the fidelity of radar echo signal simulation.Simulation results are close to the display of real radar echo.
